Bitcoin sync very slowHow can I speed up Bitcoin Core syncing? : Bitcoin
Back up your wallet just as good practice before an upgrade. Upgrading will have no effect on you receiving a payment. The new version should just take over where the old left off.
If a payment has been sent and confirmed by a miner to an address from this client, you've already "received it", you just need to catch up with the Blockchain to so the client can verify that you've received it. Your wallet needs to sync up to the date of the payment before it recognizes it and displays it to you. That's true whether you're on 0.
Dont qoute me on this, but i think the initial sync is cpu intensive. So if you want to speed it up, my only concern is upgrading the CPU, but i guess thats not the kind of answer you are looking for. It takes some time. I've always wondered why there are no easy ways to "import" the blockchain from a trusted source, and then download and verify from that point. For example, to load the blockchain from my workstation to my laptop. I'm sure it's possible, but every time I've tried, I've ended up annoyed.
You don't need an import process. Just copy the. If you store the blockchain on HDD. Stop the bitcoin client - defragment - start the bitcoin client again.
You will be surprised from the difference! Run it more often. If it's 26 weeks behind, then you haven't synced it in at least 26 weeks. I agree but this might not fit into the patterns of behavior of how people use their computers. Many people shut down their computers in the evening and start them up again next time they want to use them.
That's why I've been thinking about the lightweight-wallet-connected-only-to-your-node model. People could run an always-on node on some server in their home and sync to it from their laptop when they want to use bitcoin. I mean, gold 1. Having to keep maintenance on some weird program is a problem pretty unique to bitcoin that no other type of money really has issues with. I'm not blaming you but the bitcoin community should be aware that bitcoin's security model relies on most of the real economy being backed by full nodes.
If everyone runs a lightweight wallet then bitcoin will die. This means we should be very very careful before doing anything that makes it harder to run a full node and using it as a wallet; like raising the block size.
You can blame me if you want, I don't mind. From a practical standpoint, I'm an infrequent bitcoin user, and bitcoin core makes that a relatively painful thing to be. Three days later, when my balance was accessible again, I sent my coins to a new address generated in Electrum. It's entirely understandable. My post above is more meant towards the rest of the community, some who don't seem to see this as a problem at all.
I don't think "most" is quite right. There should be enough full nodes such that it's really easy for SPV nodes to find some, and such that a Sybil attack has an extremely small chance of giving an SPV client a view of only nodes that the attacker controls. Using a full node as your wallet is the only way to know for sure that none of bitcoin's rules have been broken.
Rules like no coins were spent not belonging to the owner, that no coins were spent twice, that no inflation happens outside of the schedule and that all the rules needed to make the system work are followed e. All other kinds of wallet involve trusting a third party server. SPV wallets simply trust the miners, if most the economy isn't using full nodes then the miners have a strong incentive to simply print money.
Remember that SPV wallets wouldn't even know the rules have been broken so would not be in a position to sell bitcoin and adopt another currency. The beauty of Bitcoin is that it allows people who want to run full nodes to run them, and it allows people who don't and who are OK with trusting the majority of hashpower to still get some benefit from Bitcoin. Which of the below situations do you prefer and why? Imagine the cost to run a full node is the same in each case:. From my point of view the actual numbers are only a loose metric, what matters is the amount of the economy backed by full nodes.
The Core team is worried that so few people run full nodes, but the first experience of a user who tries to run it involves not being able to use the software for a day or more.
This is the kind of thing that makes people flee to other wallets. Or when a user doesn't run Core for a while and starts it up, they need to wait multiple hours for it to catch up. IMO, Core should fall back to SPV security when it isn't caught up, with some indication to the user that the chain isn't synced and validated yet, but that they can proceed with reduced security if they want. Is this a change that the Core devs would merge?
It cannot find UTXOs without downloading the whole blockchain. It can download first and validate later, but still, it won't be an instant sync. Get a faster computer. Or you know download an already premade copy of the blockchain?
Hahaha this is funny but I see it like this: The Bitcoin adoption is like core client syncing: - the ones that start earlier, they already have a BTC stash but also the core client up to date - the ones that are waking up now quite late discover that only 5 millions BTC remain to mine and also they have to sync their client core. When we the early adopters was speaking loud about BTC everybody else laugh of us and say we are crazy nerds.
Now they come to take the remaining crumbs and also they have to sync the whole core like a "prize" for their ignorance. Now the show just start: we will see people trying to catch some satoshis, like zombies a piece of meat. And I will really laugh to those who I told them years ago to take some BTC and they laugh of it, that now they will come to beg some satoshis from me.

Any idea what the issue might be? I am running v0. I have already changed cache memory to MB but that didn't change anything. Bitcoin Core is capable of full sync in a relatively short period of time depending mainly on the hardware. Most of the work done is not actually downloading the blocks, it is validating them and every transaction that they contain.
It not only depends on downloading the blocks but also on the quantity and complexity of every transaction. The downloading of the blocks themselves is usually not an issue if you are connected outbound to several nodes. I am able to download blocks generally in forty-five seconds each which includes the request time etc. My upload speed is low, and latency is high. At the rate of one block per forty-five seconds, it would currently take over two-hundred-and-sixty-three days to complete the whole blockchain as there are more than blocks as of writing.
From my personal experience, the initial sync actually took over five days to complete on a 2. Performance of initial sync largely comes down to the individual performance of your computer, provided your internet is fine. Always use the latest release version of Bitcoin Core includes bitcoin-qt and bitcoind downloaded from the official site at www. An upgrade is safe and easy, just safely exit Bitcoin Core first and make a new secure backup of your wallet.
There are some parameters that you can look at and consider depending on your system. Always make a backup of your wallet before making any changes. The parameters can be entered at the command line or generally in your bitcoin. Some things to consider that could make a difference:. I am presuming here that you are running bitcoin-qt which is the GUI version and not bitcoind. If parameters are used in the bitcoin. After the initial sync, you can revert these settings to their defaults but probably leave your datadir wherever you put it.
The same as anytime you want anything fast on a computer. In the real world, and from personal experience, using an SSD increased sync speed more than 10x on my example system from the performance noted above. Real life example of varying system performance: I know someone personally who had to work on a quite large, but not extraordinarily large, Illustrator file.
Just for kicks he thought he would try the same file on a bog standard PC, opened it in Illustrator and it was completely normal. The opposite result is probably true for some operations. Also note, I have observed that exiting and restarting Bitcoin Core during initial sync seems to speed it up a bit for a while once it connects to nodes again. Referencing again personal experience, syncing on Windows 10 bit seems to be orders of magnitude faster than syncing on Linux on the same hardware - even if Windows is running in Gnome-Boxes, it easily churns through blocks per second during the initial stages of download.
If you are in serious trouble waiting to sync Bitcoin Core a full node client and you do not need the additional features that Bitcoin Core provides then, you may consider trying Electrum not a full node client which does not need to do the initial sync. On Fedora 27, getting Electrum is as simple as sudo dnf install electrum. Here's a quick fix to alleviate your issues. Manually specify peer IPs to console.
You can get node IPs from a public node directory, such as Bitnodes. Amazon, Google, etc. It should increase your speed a bit since those nodes will assist you with peer discovery. Use the latest release 0. I read the very helpful answer of Willtech and derived the following command:.
This resulted in a sync time of roughly 2 weeks on that PC. Very long indeed but much better than having to buy new hardware For some reason some nodes does not give you any blocks when you are connected to them.
If a node does not give you any data just ban it by right clicking and selecting "Ban for 1 hour" do this until you are connected to a node that actually sends you blocks. Normally just waiting will eventually resolve this issue but banning nodes until you get connected to some fast ones is a much faster way.
